Maybe you guys can help with this question:
Where do all the gust lines originate on the vn diagram?
a. v=0 n=0
b. v=vs n=0
c. v=
vb n=+1
d. v=0 n=+1
The answer is supposed to be (a), but there seems to be some doubt as someone has pointed out that on a gust envelope diagram all the gust lines cross at v0 n+1.
A word from the wise men?
